Description
It is used to detect/evaluate functionality of amino peptidases. The compound is used in an ELISA assay to detect biological functionality of chicken amino peptidase produced by E. coli. It is also employed to characterize the native IRAP (placental leucine amino peptidase). Leu-pNA, Chromogenic Substrate is documented for use with pure samples as well as cell extracts in vitro.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
